f3d59ec1c1 Working on the new library design. 
Added implementation of atomic ops with gcc __atomic intrinsics.
Implemented the unified atomic interface. Extracted atomic_flag to a
separate header. atomic_flag now follows standard requirements for
static initialization, if possible.

e3536bec75 Hopefully, fixes #9447. 
Cleanup of the success flag in CAS operations has been reworked. The
flag is automatically cleared by default and only set when the operation
succeeds. Also minor code reformatting and __volatile__ specifications
to prohibit the assembler code moving around.

1ee6311ea4 Silence GCC -Wcast-qual warning 
Use C++ casts instead of C-style casts in order to silence warning about casting away qualifiers.

b8cd09c50b Switched to boost::detail::lightweight_mutex instead of boost::mutex from Boost.Thread to avoid false dependencies on Boost.DateTime, Boost.Chrono and Boost.System. This should hopefully resolve linking problems on MinGW.

9cab8a9ebf Added a generic atomic<> implementation based on the new __atomic intrinsics available in gcc 4.7 and clang 3.2. The new implementation adds support for 128-bit atomic. Other implementations updated to employ new macros in Boost.Config for defaulted and deleted functions (this is not complete yet). Fixed padding for the lock pool. Initializing constructor for atomic<> made explicit to avoid ambiguities of different overloads of operator=.

f9c4249c8e 1. Fixed compilation with MSVC 2003. 
2. Fixed incorrect reinterpret_casts in constexpr constructors that could result in buffer overruns. The initializing constructors for non-integral atomics are not constexpr yet because memcpy must be used inside.
3. Made atomic_flag default constructors constexpr. This is not by the standard but we do not implement ATOMIC_FLAG_INIT yet, so the default constructor is needed and it should be constexpr when possible.
4. Fixed a few syntax errors and cleaned up the code a bit.
5. Moved operator value_type() to the interface class in order not to duplicate it in base_atomic specializations.
6. The return type of operator=() changed to follow the standard.
